The sublimation materials unit focuses on exploring silicon carbide semiconductors, graphene, other low-dimensional materials, and their energy and environmental applications.
The group is internationally recognized with its expertise in sublimation growth of silicon carbide (SiC) and graphene growth on SiC substrates, particularly the cubic silicon carbide (3C-SiC) growth of bulk like material with high structural quality.
The unique sublimation growth equipment in Sweden is a strong prerequisite of further technological developments. In 2011 the spin off company Graphensic AB for production of high-quality, wafer-scale graphene on SiC substrates was launched.
The group also focuses on exploring graphene, 3C-SiC, and other materials for a direct conversion of solar energy into the renewable energy such as hydrogen and other chemical fuels based on photocatalytic and photoelectrochemical (PEC) water splitting and PEC CO2 reduction. It also aims to tailor material properties for novel sensing, catalysis, and optoelectronic applications.
